Quantifying Matter: The Mole and Stoichiometry · Stoichiometry

Stoichiometric Calculations

Using balanced chemical equations to predict the amounts of products formed and reactants consumed.

Key Questions

  1. 1How do the coefficients in a chemical equation represent the conservation of mass?
  2. 2What causes a reaction to stop before all reactants are consumed?
  3. 3Why is the actual yield of a reaction often lower than the theoretical yield calculated on paper?
